1. Subsection (1) of the present section recognizes that the essence of a contract providing for payment before inspection is the intention of the parties to shift to the buyer the risks which would usually rest upon the seller. The basic nature of the transaction is thus preserved and the buyer is in most cases required to pay first and litigate as to any defects later.

2. "Inspection" under this section is an inspection in a manner reasonable for detecting defects in goods whose surface appearance is satisfactory.

3. Clause (a) of this subsection states an exception to the general rule based on common sense and normal commercial practice. The apparent nonconformity referred to is one which is evident in the mere process of taking delivery.

4. Clause (b) is concerned with contracts for payment against documents and incorporates the general clarification and modification of the case law contained in the section on excuse of a financing agency. Section 5-114.

5. Subsection (2) makes explicit the general policy of the Uniform Sales Act that the payment required before inspection in no way impairs the buyer's remedies or rights in the event of a default by the seller. The remedies preserved to the buyer are all of his or her remedies, which include as a matter of reason the remedy for total nondelivery after payment in advance.

The provision on performance or acceptance under reservation of rights does not apply to the situations contemplated here in which payment is made in due course under the contract and the buyer need not pay "under protest" or the like in order to preserve his or her rights as to defects discovered upon inspection.

6. This section applies to cases in which the contract requires payment before inspection either by the express agreement of the parties or by reason of the effect in law of that contract. The present section must therefor be considered in conjunction with the provision on right to inspection of goods which sets forth the instances in which the buyer is not entitled to inspection before payment.
